Lyme Disease Lyme Disease Is Caused by Ticks. More Specifically, Lyme Disease

Lyme Disease
Lyme disease is caused by ticks. More specifically, Lyme disease is caused by Borrellia bacteria, which are carried by ticks. When ticks infected with this bacteria bite humans, the bacteria can be transmitted into the bloodstream, causing an illness known as Lyme disease.
The symptoms of Lyme disease include fever, headache, fatigue, and joint and muscle pain. One of the most noticeable signs is a rash that looks like a series of red rings radiating out from the bite. This usually appears a week after the tick bite. However, not everyone with Lyme disease gets this rash.
The good news is that Lyme disease can be treated with antibiotics. Most people recover quickly and fully. However, if Lyme disease is not treated properly, patients can suffer from debilitating symptoms weeks, months, and even years after the bite. This condition is known as post-treatment Lyme disease (PTLD) or chronic Lyme disease (CLD) .
To protect yourself from Lyme disease, always cover your skin with clothing or insect repellent when hiking or camping. If you get bitten by a tick, remove the tick right away; most cases of Lyme disease require the tick to be attached for 36 to 48 hours. If red rings appear, see a doctor right away. Lyme disease can be harmful, but it is preventable and treatable with early intervention.
